COMPARITIVE STUDY OF THE PROPERTIES OF FLY ASH CLAY BRICKS AND CLAY BRICKS 1Ramji

Porwal Department of Civil Engineering, Madan Mohan Malviya University of Technology, Gorakhpur, India Email: ramporwal123@gmail.com Abstract: Brick is one of the most widely used construction materials throughout the world since ancient time. Fly ash clay bricks are one of the best alternatives to the conventional burnt clay bricks. This dissertation gives the results of an experimental investigation in which the compressive strength, water absorption, density and durability of Fly ash-clay bricks are investigated by using varying quantities of fly ash with partial replacement of clay. The properties of Fly ash clay bricks are compared with those of the ordinary burnt clay bricks. The results indicate that these bricks are lighter in weight, durable in aggressive environments and have sufficient strength for their use in building construction.
